Numerically exact solution of the many emitter – cavity laser problem: application to the fully quantized spaser emission — •Michael Gegg, T.

Open many body quantum systems consisting of N quantum emitters (QEs), e.g. dye molecules or quantum dots, coupled to a lossy cavity/optical mode have been subject to extensive research for decades. These systems are described by a Tavis-Cummings/Dicke model in the Lindblad formalism for open quantum systems. This provides access to a manifold of interesting applications, such as lasers, parametric amplifiers, atomic coherent states etc.

For instance, in the field of quantum plasmonics, the model system was utilized to address the feasibility of spasing – i.e. surface plasmon amplification by stimulated emission of radiation. In this context, we develop an exact and numerically scalable solution to the Tavis-Cummings/Dicke Lindblad equation.
